Guillain-Barre syndrme (GBS) has several subtypes that are divided by clinical, electro- physiological, and pathological findings. A novel form of GBS, that is termed acute motor axonal neuropathy (AMAN), is characterized by the selective involvement of motor fibers, and is associated with anti-GM1 antibodies. A 8-year-old male patient were developed ascending, symmetrical paralysis, and areflexia, but no sensory disturbance. Elevated titers of serum IgG anti-GM1 antibodies were detected. His thoracolumbar spine magnetic resonance imaging (MRI) revealed thickening of cauda equina and enhancement of anterior nerve roots of T12-L1 spinal level after Gd-DTPA infusion. Electrophysiological diagnosis was acute motor axonal neuropathy (AMAN). We report this case with review of the literature.
